ProgressNo skill scores yet

Understand and use the sine, cosine and tangent functions; their graphs, symmetries and periodicity.

Knowledge of graphs of curves with equations such as y=sin⁡xy = \sin{x}, y=cos⁡(x+30°)y =\cos{(x + 30°)}, y=tan⁡2xy =\tan{2x} is expected.

Know and use exact values of sin⁡\sin and cos⁡\cos for 0, π6\dfrac{\pi}{6}, π4\dfrac{\pi}{4}, π3\dfrac{\pi}{3}, π2\dfrac{\pi}{2}, π\pi and multiples thereof, and exact values of tan⁡\tan for 0, π6\dfrac{\pi}{6}, π4\dfrac{\pi}{4}, π3\dfrac{\pi}{3}, π\pi and multiples thereof
